Montana Geology 2014 Calendar
This year's calendar is of Capitol Rock in eastern Montana, one of ten National Natural Landmarks in Montana. Capitol Rock is so named for its resemblance to the U.S. Capitol Building. The nearby town of Capitol was established in the 1880s, and the area is known for some spectacular fossil finds, some housed at the Carter County Museum.
Most of Capitol Rock is Arikaree Formation, light-colored, volcanic-ash-rich sandstone or quartize deposited millions of years after dinosaur extinction. Its resistance to erosion has left it as a caprock, creating the distinctive shapes and preserving the underlying rock.
Read more about the geology of Capitol Rock—including the puzzle of the steeply dipping beds below the Arikaree Formation—and the history of Capitol and the surrounding area in our 2014 calendar.
Coalbed-Methane Basics — Ten years of Lessons from the Powder River Basin, Montana
The Montana Bureau of Mines and Geology's 2012 publication Information Pamphlet 6, "Coalbed Methane Basics: Ten years of lessons from the Powder River Basin, Montana," by Elizabeth Meredith, John Wheaton, and Shawn Kuzara has won the John C. Frye Memorial Award from the Association of American State Geologists and the Geological Society of America.
The John C. Frye Memorial Award was established in 1989 by the AASG and the Geological Society of America to support the growth of environmental geology, which has steadily risen in prominence over recent decades. The Award is given each year to a nominated environmental geology report published in one of the three preceding calendar years either by GSA or by a state geological survey. A monetary award and a certificate to each author is presented at the AASG Mid-Year meeting, held at the GSA annual meeting.
John Metesh, Director of the MBMG, said: "We are very proud of our group from the Billings Office of the MBMG. As the title suggests, this publication represents a lot of good work over many years."

Sapphires in the Butte-Deer
For anyone who is enthusiastic about sapphires.
This stunning, full-color publication describes the sapphire deposits and occurrences in the area north and west of Butte. The identification, size, shape, color, and mineral inclusions of sapphires in the area are discussed, with photos throughout.
Probabilistic Earthquake Hazard Maps for the State of Montana
of the potential earthquake threat to dams in Montana, a set of
probabilistic earthquake ground motion maps have been developed
for the Montana Department of Natural Resources and Conservation
(DNRC) Dam Safety Program.
The maps display ground motions for two site conditions: soft rock and the ground surface. In addition to the ground shaking maps, a set of 6 maps have been developed to aid DNRC and practicing engineers in the analysis of site response and liquefaction potential. These maps display the modal earthquake magnitude and modal distance of the magnitude–distance distribution that contribute to the hazard at a specified location for the three return periods.
